well not in rear wheel drive any way. closest would have to be mx5/miata but still a struggle for 6 foot plus peiople.

r32 gts t's are going cheaper than 180sx and silvias still. good bang for the $$$.

If you want datsun still, 260z but more realistically 280z would be achiveable, or stanza/180b but they would be near or over the 1000kg.

Mazduh rx3/capella but $$$$ as all the rotor heads want them.

There is nothing sub-100kg that is as fun as a 1200, yet roomier.

Keep dreaming.

Ther was a R29 (posably?) pre R30 import anyway's at my local mechanic with an RB20dett and that thing flew as it was a whole lot of motor for a reasonably small/light car and it was comfy as to sit in..

Only thought I had so far is old six cylinder datto with a four cylinder engine fitted etc Eg the old skyline model after the 240k with a nice strong CA or SR but thats probably not much of an improvement on the Sunny with the same mods

strip out a R32 skyline or sylvia or 180sx.... these are all fun cars and can be made reasonably light and they are in the datsun/nissan family. my personal choice would be a 91 model navara king kab ute with sr20det conversion but thats over 1000kgs.

Have been starting to get the idea I would like a new version of my 1200
Dare I say it being over 6foot and driving a 1200 is getting a bit of a chore for everyday driving and it has become a weekend drive only and my upgrade so far is a Sunny coupe
Here is the Question
What can I build sub 1000kg that is as fun to drive as the 1200 but easyer to live with as the sunny is not quite enough
